JavaScript equivalent for PHP preg_replace

Question

I've been looking for a js-equivalent for the PHP preg_replace function and what I found so far is simply string.replace.

However I'm not sure how to convert my regular expression to JavaScript. This is my PHP code:

preg_replace("/( )*/", $str, $str); 

So for example the following:

test   test   test test 

becomes:

test-test-test-test 

Anyone knows how I can do this in JavaScript?

Answer 1

var text = 'test   test   test test'; var fixed = text.replace(/\s+/g, '-');
